ATTACHMENT FO GAS lm'G-INES.

` Application led July v23, 1923. Serial No. 653,280.

To all whom t may cof/wem.'

Be it known that I, JosnPH P. MEYER, a citizenof Germany, residin atMapleton, in the county of Monona, tate of Iowa, have invented certainnew and useful Improvements in Attachments for Gas Engines;- and I dohereby declare the following toi'be a full, clear, and exactdescription.

of the invention, such as will enable others make and use the same. Thisinvention relates to new and useful im'provements in attachments forautomobile gas engines, and particularly Ito devices for controllingthe. flow of the gaseous mixture 'to the intake manifold.

One object of the invention is to provide a device'which is arranged tobe placed between thel carburetor and the intake manifold, for thepurposeV of causing the gaseous mixturetobe dischar into themanifold 1san elevation of a portion of a invention therein.

Figure 2 is an enlarged horizontal sectional view on the line- 2 2 ofFigure V1, taken just above the aperturetf plate. Figure 3 is a verticaltransverse sectional ,40 view through the aperturedplate.

Figure 4 is a plan view of a modified form v ofv plate, wherein areinstead of openings. Figure 5 is a vertical transverse sectional view onthe line 5 5 of Figure 4. 4

Referring particularly to the accompanying drawing, 10 represents ayportion of a carburetor, and 11a portion of-an intake manifold, Vthesame being rovided withthe 5 0 apertured flanges 12 13,-' res ectively.Disposed between these flanges, an secured provided parallel bars in'placev by the bolts 14,. which also pass' through the flanges 12 and-13,is a metal plate 15. The portion ofthe plate 15, whose skilled in theart to which it appertains to l carburetor and intake manifold, showingthe area equals the area of the bores of the carburetor andintakemanifold, is formed with a plurality of openings 16 of conicalform, thesmaller ends being uppermost, or at the upper face of the plate. Formedthrough one edge of the plate 15, and communicating with .several of theopenings 16', are the openings 17, and located in' each of. theseopenings 17 is a spring pressed air intake valve 18, said valve beingarranged to open inwardly toward the openings 16, to permit 'atmosphericair to pass into the gaseous .mixture as it flows to the intakemanifold.

By forming these openingsv 16 of conical shape, the gaseous mixture willbe reduced in area, and injected into the intake manifold in very finestreams, whereby the engine cylinders will receive the proper amount ofmixture for the successful operationof the engine, and thereby obviatethe injection of a mixture which is too rich.l

In the form shown in Figures 4 and 5, in-

stead of forming circular openings in the plate 19, ,there are formedtransverse parallel slots 20,- in thearea of the plate corre-- spondingt0 that in which theopenings of the first form are made, rthe resultantbars 21 beingapproximately triangular in cross section, as seen in Fi re5, so that the slots will benarrow at t e upper sides and wide at thelower sides, the gaseous mixture passng'from these slots, inrto theintake manifold, in very thin sheets. Formed through one edgey of theplate 19, are openings 21, similar to' the openings 17, and in each ofthese openings is located an inwardly Aopen-V in s rin ressed valve22,`for permitting atrgnosrphelgicpair to be drawn into the adjacentslot of the plate,` in a manner similar to that of the first form.

Itv will be understood that, although lI have villustrated the deviceasformed with circular openings and slots, the diameter of the openings,and the Widths of the slotsmay be varied according to the conditions ofthe work, or the desire of the user. Thus by using plates with Aopenin's or slots of different sizes, the amount o gaseous mixture which wlllpasstherethrough, will be governed, and the speed of the enginecorrespondingly controlled.

What is claimed 1s: 1. An attachment for a gas engine comprising a.plate interposed between the carl A f y 1,503,371'
